To all whom it may concern Be it known that I, JOHN W. Konnunrr, acitizen of the United vStates, and a resident of Chicago, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in Carcass Polishing and Cleaning Mechanisms; and I dohereby declare that the following is a full, clear,

and exact description of the same, reference being bad to theaccompanying drawings, and to the letters of reference marked there-'on, which form apart of this specification.

The present application constitutes a division of my prior applicationfor patent for carcass scraping, polishing and cleaning mechanisms,Serial No. 384,287, filed July 17 1907.

This invention relates to improvementsin scraping mechanisms andparticularly to that class adapted for scraping, polishing and cleaninghogs.

Heretofore in carcass scraping machines the carcasses have beensupported on or suspended from a suitable conveyor and passed betweenscrapingdevices suitably arranged to act thereon. Where the carcassesare supported lengthwise on the con veyer there has always been a stripextending the entire length the carcass that could not be acted upon bythe scraping mechanism and in that where the hook engages that is notscraped.

Furthermore machines employing conveyers which necessitate carriagesand-hooks being used for engaging the carcasses are quite expensive toinstall, requiring considerable space, constantly need repairing andconsist of a multiplicity of parts.

It is an object of this inventionto provide a construction in whichmechanism is provided capable of both conveying the carcasses past thescrapers and constantly, rotating the same simultaneously for exposingall parts to the action of the scrapers and in which the use of hooks'forengaging the carcasses canbe dispensed with. Alsqthe hog scrapingmechanisms heretofore. have only been adapted to clean the carcass, andhave not in any way aided in. forcingthe carcasses'through the machine.

It .is an object of this invention to provide a carcassscrapingmachinein which the use of a coiweyer neeessitatitrgtheluse of books andcarriages lselimina' It is a further object of this invention to providea machine in which the carcasses are moved past the scrapers at thedesired rate or may remain in one place in the machine until completelycleaned and in which the carca'ssesare continuously rotated or turnedthereby exposing all parts to the action oi the scrapers and to providea scraping device in whichit is practically impossible to dislodge acarcass while being acted upon by the heaters.

It is a very important object of this invention to provide slpiralrolls, drums or cyl inders or plain rol s or drums with spiral rings,bars, bands, etc.,secured thereto for supporting the carcasses, movingor conveythrough the machine and may beset for any maximum rate oftravel desired for the carcasses so that even though the velocity of therolls should exceed the limit desired for most eificient scraping, yetin which the resilient or flexible spirals will yield to prevent thecarcasses from moving faster than the desiredrate.

It is an exceedingly important objectof this invention to provide amachine of the class specified in which a p'lurality of spiral.

rolls having the same or differently formed convolutions thereon, areused conjointly for supporting, conveying and rotating the carcasses,orin which a roll and conveyer are conjointly used for this purpose.

It is also an important object-of this invention to provide a machine inwhich flexi- 'ble; scraping. mechanisms are employed, and in which thescraping mechanisms coact with the aforesaid conveying or moving androtating mechanism for forcing the car-' casses throu h the machine.

Itis also an object of this invention to provide a device of the classspecified in. which the rotating and movmg carcasses are 1 partlysubmerged fluid {at a suitable'temperature whereby the hair, dirt andrefuse It is a further object of this invention to provide ahighlyefiicient and greatly simplified machine of both small and greatcapacity and the capacity depending upon the arrangement of the rollersand scrapers.

Itis finally an object of this invention to provide a durable machine inwhich delicate mechanisms and parts are entirely avoided and whichrequires minimum number of attendants;

The invention consists of the matters hereinafter described and morefully pointed out p and defined in the appendedcla-ims.

In the drawings: Figure 1 is a longitudinal, vertical section of adevice embodying my invention, with the scraping mechanisms arrangedtransversely the travel of the carcass. Fig. 2 is a top plan viewthereof. Fig. 3 is a transverse vertical section of a device embodyingmy invention, in which the beaters, rotating and moving mechanisms arearranged longitudinally of the machine. Fig. 4 is a top plan view. Fig.5 is a section similar to Fig. 3, with the heaters arranged differently.Fig. 6 illustrates the moving and rotating rolls or drums employed in Fis. 3 and 4. Fig. 7 illustrates the moving and rotating rolls or drumsemployed in 5. Fig. 8 is a modified form of a device embodying myinvention, having the mechanisms inclined. Fig. 9 is a detail of thewedge blocks. Fig. 10 is a verticalsection taken through Fig.

As shown in the drawings: A, indicates a scalding vat or tankconstructed of any suitable material and size, and having the rearbottom wall a thereof inclined up-- wardly and rearwardly. Journaled inthe sides of the tank at the upper and lower ends of said inclined walla are shafts (l -a on which the elevator a is sup orted. Adjacent therear end of said scal ing tank A, is a water tank B, provided withsuitable water inlet 6, and steam or heating fluid b, and with asuitable washout pipe or plug 6 Said tank B, is, constructed of sheetmetal or any other preferred material and comprises a. bottom wall 12?,side walls 6 and end walls b b 2E 21). height, width and length tocontam A e variousmechanisms therein. The wall I), of the tank B, isplaced against the top of the inclined wall a, of the scalding vat andis provided with a swinging or automatically cldsing door 1), above thetop of the inclined wall of the scalding tank, which is of a length toadmit the hog lengthwise therethrough from the con'veyer a Rigidlysecured to the side walls I), and end wall I), of said tank is aninclined platform b, which extends rearwardly from the bottom of thedoor opening and the lower end thereof is directed horizontally or at aslight angle upwardly. J ournaled in the side walls 12 of said tank B,is a beater shaft C, on which are bolted or otherwise rigidly securedflexible beater arms 0, constructed of any suitable material such ascanvas, chains, rubber or other flexible medium. A flat plate 0', ofsuitable length is secured at the lower end of the beater arms and acurved plate 0 is secured thereagainst by means of rivets or in anyothersuitable manner which strengthens the lower end of the arms and preventsshort bending. vRigidly secured to the outer ends of said beater arms 0,are a plurality of sets of flexible or rigid blades c -cc having theirouter ends curved outwardly,

and, as shown, arranged two abreast but.

obviously any number may be used in a set.

Journaled in suitable bearings 1n the side walls 6 below and at the'rearof the beater shaft C, is a roll drum or cylinder D, to which arerigidly secured in any preferred manner, bars or plates d, of suitablemetal or other material, which are shown as angle irons secured to theroller by one flange, and the other flange is directed radiallyoutwardly and parallel the axis of the drum. A suitable driving pulleyD, is secured to the drum shaft (Z at one end and sprocket wheels dl arerigidly secured to the beater shaft 0, and drum shaft d of the drum D,outside and at the opposite side of the tank, and a chain (1*, istrained therearound, which drives the heaters.

Above and slightly to the rear of the rear of the center of the roll ordrum D, just sufficiently for the bars'd, to pass, is a platform (iwhich is shown as horizontal to the end wall 12 of the tank and is theninclined downwardly to deliver the scraped and cleaned carcasses bygravity upon the operatingtable or bench X.

A partition E, is secured to the side walls b*, of the tank 'B, abovethe latform (Z and pivoted theretois a door 6, curved tpward theopposite end of the tank and provided with a spring latch e', normallylocking the door in closed position. A cable or cord 6 trained aroundsuitable pulleys e ee is secured to the latch e, and extends -withinconvenient reach of an attendant for opening the door toadmitthe-cleanedcarcass through the opening in the end wall I)", uponthe platform X, and if desired a suitable strip of flexible material e,such as canvas or swinging doors may close said exit.

In. the constructions illustrated in Figs. 3 to 7 inclusive, themachines are arranged for large capacity and the scalding vat anddelivery platform may be the same as shown in Figs. 1 and 2, or anyother form, and preferably automatically closing doors are employedsimilar to those before described or" suitable'ourtains or aprons as 6.Supported on suitable uprights or posts is a water tank F, havingsuitable side and end walls ff'f and which is provided with steam, waterand clean-out pipes and valves as before described. Said beater arms 9,as shown clearly-in Figs. 3 and 4,. are inclined outwardly at a suitableangle longitudinally with the shaft toward the delivery end of themachine by means of wedge blocks H. Said wedge blocks, as shown in Figs.9 and 10, are provided with a straight edge h, which is concaved toconform to the convex surface of the shaft and the opposite side It, isinclined at anangle depending upon the desired angularity of theheaters. The wedges are secured on the shaft between the beater armshaving their apexes directed, as shown, toward the entrance to themachine, and bolts rigidly secure the wedges and beaters in oppositelydisposed pairs on the shaft, as shown clearly in Fig. 4. J ournaled inthe end walls f, of the tank below the beater shaft G, are spiral rolls,drums or cylinders K K' each having gudgeons or shafts in the endsthereof which extend through suitable watertight journal boxes beyondthe ends of the tank. 'Said rolls or cylinders K-K', as shown in Fig. 6,are constructed of metal, wood, canvas or other suitable material. Theroll or drum K, is provided witha bar, strap, or band is, of metal orother suitable material coiled spirally around the roll in the form of ahelix and which extends from end to end of the roll. The roll or drum K,is provided with a bar, strap or plate is, of metal or other suitablematerial and is shown as an angle iron which extends longitudinally ofthe roll or drum and is curved partly therearound forming a spiralrollor drum. The bands, straps, bars or coils are constructed in two forms,namely, rigid spirals or bars, which are made of material such as steelor other non-yielding material and resilient and flexible spirals orbands constructed ofspring steel, rubber or other suitable material,-theobject of which will be hereinafter described.

' It is to be distinctly understood that in the construction shown, anyform of roll or drum may be used and either flexible. or rigid bars orribs .may be used with any form of drum. The specific construction der,and either yielding or non-yielding ribs. On the other hand, in thesmaller plants where one hog is operated on at a time, either a metal orother cylinder may be used with either yielding or non-yielding ribs,and the construction for any user may vary to meet the exigencies of thespecific case,

I do not claim the combination, in a hogdehairing machine, of: apower-driven rotating shaft having beaters borne thereon; andcooperatively power-driven and rotarilyacting conveyer-mechanism adaptedto freely and completely support the carcass and at the same time 'rollit laterally and advance it longitudinally while presenting it to thesimultaneous dehairing-action of the scraperniechanism, said carcassbeing free of any grappling to the advancing means; saidconveyermechanism including a plurality of mutually parallel andsimilarly rotating conveyer-rollers, which are disposed in asegment-formed group concave to the beater shaft, and whose respectiveaxes of rotation are substantially parallel to the aforesaidbeater-shaft and extend in the direction in which the carcass isadvanced; which is a combination claimed in the Hannaford Patent No.1016495, issued February 6, 1912, on an application that has beenco-pending with my present application; and I do not claim thiscombination because I am not the inventor of it, as the drawings andspecification of my present application do not show the segment-formedgroup of conveyorrollers shown, described and claimed in said Hannafordpatent, but show and describe only a single pair of conveyer-rollers andnot the three or more conveyer-rollers necessary to form thesegment-formed group shown and described and claimed in said Hannafordpatent.

Any suitable driving mechanism may be employed, but, as shown in Fig. 4,and dotted lines in' Fig. 5, sprocket wheels f /"*-f f, are secured onthe ends of the drum or roll shafts and beater shaft respectively andactuate the drums or rolls K and K and the heaters in the samedirection, as

shown by the arrows in Figs. 3 and 5. Thus the beater striking thecarcass moves in an opposite direction to the drums or rolls.

Guards LL are secured on each side of the tank and inclined downwardlyto a point approximately over the center of the rolls and allow thespiral to nicely clear the same. As shown in Fig. 5, both rollers M-M'are similar to the spiral roll or drum K, before described.

In the construction illustrated in Fig. 8, the tank N, is inclinedtoward the delivery end and is provided with a suitable outlet of, atthe lower end thereof, adapted to deliver the refuse and hairtherethrough into a receptacle from which it is delivered to anysuitable place, and a water supply tank K is situated beneath the tankby means of which water is supplied to clean the carcass by any suitablemeans. The spiral rollers O, are inclined longitudinall of the tank, asis also the scraper shaft and the beater arms p, are arranged thereon asbefore described with reference to Fig. 3. The drive is similar to thatbefore described.

The'operation is as follows: The construction illustrated in Figs. 1 and2, is for a small capacity machine. The hogs, after being suitablyscalded in thevat or tank A, are moved upon the elevator a which deliv-'ersthem through the door 6, and. the carcasses move by gravityto the endof the platform b and upon the roller D. Inas- 'much as the bars d, areparallel with the axis of the roller upon rotation thereof the bars 'ateach revolution engage the hog and rotate or turn the-same continuously.The hog is not moved longitudinally, inasmuch as the roll or drum is notspiral and the scrapers which rotate oppositely from the direction ofrotation of the drum whip and 'scrape the hair and refuse from thecarcass as the same is bein rotated. The beaters prevent the carcass frombeing thrown rearwardly from the rotating drum -and the rigid door 6,prevents the carcass from being moved by the beaters forwardly beyondthe roll, so that at all times the carcass is continuously turning inposition for the heaters to act continuously on all parts thereof. Thewater level in the tank may be any preferred height, but is shown asslightly above the roller D, approximately on a level with the middle ofthe carcass so thatthe carcass is lying and-rotating in water (which isheated or not, as is found necessary) and the heaters acting thereon notonly scrape the bristles therefrom, but polish the carcass. After thecarcass is thoroughly cleaned, the cord .9 is pulled, releasing thecatch and opening the door and the carcass is forced upon the platform(l gand is delivered by gravity upon the operating table or bench Thecord is released, and the operation repeated.

The construction shown in Figs. 3 to 7 inelusive, is a larger capacitymachine, and

rollers and beater shafts extend longitudinally of the machine. Aplurality of spiral rolls or drums of the same kind may be employed, or,of course, one of eachconstruction may be employed acting conjointly.Suitable doors may be provided at each end Of'the device for theentrance'and exit Of the carcass, but of course the construction ofwhich forms no part of this invention.

The operation of the spiral rollers shown in Figs. 3,4 and 6 are asfollows: The roller K rotates as shown by the arrow, to the left, andthe bars or spirals k striking the carcass constantly rotate or turn thesame inwardly upon the roller K, said roller K, rotating in the samedirection, the helical spiral forces the carcass endwise therealong at arate dependent upon the number of revolutions per minute made, and the.roll or drum K also aids in moving the carcass therea-long. At the sametime, the carcasses are being turned and passed through the tankfthebeaters g are acting thereon on all parts of the carcass, and, inasmuchas the beater arms are of flexible material, the same conform to thecarcass and a large surface of the hog isscraped by each sweep of thesets of blades. Owing to the angularity of the heaters, the same strikethe carcass and force it toward the delivery end of the machine, thuspulling the carcass along, aiding the rolls and drums. The guards L-Lprevent all possibility of the carcasses from beingdislodged althoughdanger from this source is slight. As before described, the water levelin the tank is maintainedat the desired height to wash and clean thecarcass.

It may be desired (according to various circumstances and the mode ofdrive) to use either the" rigid spiral rollers, or those having flexiblespirals thereon, and the operation in either case is the same, exceptwhere flexible and resilient spirals are used, they may be constructedfor a maximumspeed at which to pass the carcass through the tank, andwhen the revolutions of the rollers exceed a certain velocity fromcarelessness or other causes, the spirals yield and the carcasses thuscannot be forced through the machine at a greater rate than desired. Theadvantages of this are obvious, for in handling the carcasses in largequantities, the machine is operated at full speed, and, should the drivebecome too rapid, the carcasses nevertheless are passed through themachine at a rate for efficient scraping. Where two spiral rolls ofsimilar construction are-used, as shown in Fig. 5, the operaanism'includin removal of the bristle, the carcass may again be scalded .inthe tank as the scrapers. act thereon.

Many changes of construction may be varied' without departin from theprinciples of this invention, and? therefore do not desi're to limitthis application for patent as to details, or otherwise thannecessitated by the prior art.
